Title: Steel support for formwork panels - has rebate to leave concrete forming face flush with support face and butt welded together
IPC: E04G9/02
Filed: 1978-10-30
Abstract: The steel section is for framing and stiffening formwork panels, for the shuttering of concrete. A protuberance rests on the outer circumferential surface of the formwork panel with a first, short flange which forms a continuation of the protuberance and rests on the marginal zone of the inner side of the formwork panel. A second, long flange forms a continuation of the first flange and stands perpendicular to the formwork panel. A shallow, V-shaped indentation points towards the internal space of the steel section, with a third, short flange to form a continuation of the second flange. This extends outwards, lying parallel to the formwork panel and with a third flange which forms a continuation of the second flange and extends in the direction towards the protuberance.

Title: Electrolytic treatment vat - has rotatable cylinder with concentric squirrel-cage cathode and bar anode rotating with cylinder
IPC: C25D17/22
Filed: 1979-01-17
Abstract: An appts. for electrolytic treatment consists of a cylinder rotating about its axis with an opening at one end for receiving the parts to be treated and an opening at the other end for discharging the treated parts, forming a vat for the electrolyte in which the cathode and anode dip. The cathode is constituted by a conducting element concentric with the inner wall of the cylinder and rotating with it, e.g. a squirrel cage. The anode is constituted by an element positioned under the surface of the bath and extends over the length of the cylinder. Means, pref. a spiral wall, are provided for making the treated pieces progress from the inlet end of the cylinder to the outlet end. The invention remedies inconveniences of existing appts., including the large space occupied and the large number of vessels required in installations in line and the rapid decomposition, the slow rate of depositing and the handling problems in existing appts. of the drum type, and the face that the process is not continuous. The process allows continuous operation, uses less electrolytic bath, rinsing water or chemical bath and consumes less energy. The different treatment apparatuses can be combined so as to minimise the space required.

Title: Async. motor control for electric vehicle transmission - includes rectifier and oscillator between diesel driven alternator and async. motor
Inventor: MACHEFERT-TASSIN YVES
IPC: B60L50/13
Filed: 1979-02-08
Abstract: The diesel engine (1) drives the rotor of a three-phase alternator (3) whose output terminals are connected to a rectifier (4). Between the rectifier and the asynchronous electric drive motor (2) there is an oscillator (5) whose natural switching is ensured by a synchronous compensator (6) connected in parallel with the oscillator. The frequency of the current produced by the alternator (3) is of the same order as the frequency which is to be applied to the async. motor. The synchronous compensator functions at the same frequency and at a speed proportional to the frequency. It is advantageous if the speed of rotation is as high as possible, so as to reduce its size. For example when the alternator turns at 1000 rev/min. the compensator may turn at 3000 rev./min. in the opposite direction.

Title: Brazing alloy for titanium and alloys - comprises silver copper and aluminium
Inventor: FERRIERE GERARD
IPC: B23K35/30
Filed: 1979-02-27
Abstract: Method of brazing joints between pieces of titanium and its alloys at about 700 degrees C comprising using a brazing alloy of Ag, Cu and Al, the compsn. of which falls inside the triangle defined as the ternary diagram between the points (A) Ag 91-Cu 2-Al7; (B) Ag 54-cu2-A144 and (C) Ag 54-Cu 39-Al 7.

Title: Electronic control circuit for discharge lamp - includes semiconductor switch between two storage capacitors switched at higher frequency than that of alternating supply
IPC: H05B41/392
Filed: 1980-07-04
Abstract: The control circuit provides power for discharge lamps such as those containing mercury vapour, sodium, neon or metallic iodides. The circuit includes a first capacitor serving as a reservoir of energy provided by the alternating supply network. A second capacitor serves as the source of current for the lamp itself. A bi-directional controlled semi-conductor switch is connected in series between the two capacitors to allow or prevent the flow of current from the first to the second capacitor. A control circuit regulates the alternate closing and opening of the switch at a frequency much higher than that of the supply. A current limiting inductance is also connected to the first capacitor.
